About Us
Oxy-Anion Stable Isotope Consortium (OASIC) was established by Prof. Huiming Bao in
2001 at 51Âþ» (U.S.A). OASIC’s research and educational activities
are relevant to energy, environment, and human well-being. OASIC is now offering high-quality
stable isotope ratio measurement services to the greater research, government, and
industrial communities.
Research
A common thread of our research has been the use of high-dimensional stable isotope systems to "read" geological, biological, and environmental records, with a special interest in the history of our evolving atmosphere.
The tools that we use include gas-source isotopic ratio mass spectrometry (dual-inlet
and conflo), laser-fluorination systems, vacuum lines, GC, IC, ICP-ES, SEM, XRD, and
wet- and photo-chemistry lab facilities. OASIC has built up a unique stable isotope
laboratory that is specialized in the isotope-ratio measurements of most elements
in water-soluble oxy-anions such as sulfate, nitrate, perchlorate, phosphate, and
hydroxide. OASIC is capable of chemical preparation and measurement of δD, δ15N, δ18°¿,&²Ô²ú²õ±è;δ17°¿,&²Ô²ú²õ±è;δ34³§,&²Ô²ú²õ±è;δ33S, and δ36S values of SO42-, NO3-, ClO4-, and PO43-with the best precisions in the community.
